From 9df38c47d01eb1fd7eb9d60ac70a4170e638b4a2 Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Tue, 12 Apr 2011 13:56:41 +0100 Subject: [PATCH] target-arm: Detect tininess before rounding for FP operations The ARM architecture mandates that we detect tininess before rounding, so set the softfloat fp_status up appropriately.
